Darkseid

While my first impulse would be to shy away from Darkseid because of Marvel planting their flag with Thanos for "The Avengers 2," I think the example we've seen with "Superman: The Animated Series" would indicate that there is a way to handle Darkseid that is far less cut and dry than many villains. General Zod sets a very high bar for whatever villains we'll see further down the line in this franchise, and at least part of that is because "Man Of Steel" makes a strong case for Zod's point of view. Doing the same with Darkseid would be a challenge for a writer, but it would also pay off in a much richer character, and the potential is certainly there. Besides, when you're talking about a real threat, Darkseid is about as big a threat as they have in Superman's rogues gallery.-Drew McWeeny
